Indians ftw. Seriously, its been quite a while since I welcomed someone from India...or maybe I haven't even welcomed a single indian yet? Bah, I guess it doesn't matter. XD;
Welcome to Pokecommunity forums, Madabi. This place is pretty big, actually. There are all sorts of people here. Many may not even like pokemon itself but are still active members. You'll have tons of fun if you're a pokéfan. If not, its still fine. XD; There are a lot of places here which you'll get to know once you spend a little time. There's a roleplay section, writings, art gallery, graphics and photography, other chat, emulation, game development...and a lot of other places. Depending on your interests, you might have some really awesome time in any of these sections. But yeah, the rule of the thumb is that you follow the rules. No matter whichever section you chose to frequent/post in, you'll have to follow the rules. Of course, that's something which goes without saying..but it'll be nice if you read the rules. Will save you from a lot of messy stuff later, trust me.
Concluding this post, I'll just advise you that if you've got any doubts, don't hesist to ask me. Or you can ask any staff member. Pretty much everyone here is really friendly and you'll feel just at home. So, hope you have fun around the forums, Madabi. See you around~
Just for the record, I'm from India too. XD;
