Evidently you're not listening.
A discussion thread is for character bios and discussing events in the RP out of character - working things out etc. That belongs in the Role Play Discussion board. The ACTUAL RP however, with in-character events etc., is meant to go on a different thread, its own thread, in the Role Play forum. What you essentially did is posted a discussion thread in the Role Play forum, had the thing moved, then started posting actual Role Play material... in the discussion thread. After being told to read the rules, which explain that sort of thing.
Clearly you didn't.
But honestly, even if you did attempt to use this post as an RP starter - it honestly leaves a whole damn lot to be desired. Aside from only being barely a paragraph and not really setting the scene for ANYTHING, how does your character know Lightning-the-emolga's character's name? If a complete stranger walked by you, would you know their name if they haven't told you what their name is? Newsflash: you would not. Character bios are a basic groundwork for the players to know who the characters are - but that does not mean the characters, in universe, would have access to that information, and your characters cannot act on that information.
If your characters know each other, that's a different story - but then you would have to actually make note of this somewhere after you've ironed details out together - you can't decide you know someone else's character without the other person's permission as that's autoing and is expressly prohibited. I don't see any indication of that, though.
"But how do I note the presence of a character and/or interact with them?", I hear you ask.
Once again. If a stranger walked past your character, what would your character notice about them? Some detail of appearance? Their mannerisms? Their behaviour? Pokemon that walk by their side? Some sort of particularly eye catching element that your character would notice and that you as a writer could work with? That's what you do. Think of your character as a real life person. They see the world as they see it. They are not omniscient or have access to the sort of knowledge you, as a writer, do - only to the sort of knowledge they, as a character do. Mind you, in this case it's a bit of a problem to do so because neither of you bothered to even throw in a MARGINAL description of your characters for the other person or other readers to go on. Your characters could be literally replaced with a piece of wood with the character name written on in crayon and no one would be the wiser. That does not make good RPing. Or good writing in general for that matter.
Consider starting your post with your own character, and their thoughts and interactions with their own Pokemon. Add some actual setting and description. So you titled the thread "Sinnoh journey". That means things could be happening ANYWHERE in Sinnoh. For all we know these pieces of wood with a character name written on could be standing right on top of Spear Pillar and being slowly chewed on by a cross-eyed Dialga as we speak. After all, that IS in Sinnoh. Where are your characters located now? What does the place look like? Feel like? How did they come to be there? What are they doing there? Anything? Anything at all?
As the person who started the thread it falls to you to actually put all that down so other people can properly interact with it. You've utterly failed to do so. Also, maybe you should wait with interacting with another person's character until they've properly posted and introduced their character?
I'm shutting this down. Please read the rules - read them, don't skim them - before trying again.
