Russian internet-speak

[scifigal.livejournal.com]

I haven't seen this posted here, so if it has, please direct me to to correct place and I'll happily delete this post.

I'm trying to figure out what are some common internet-isms that are good to know when chatting online with Russian speakers. An internetism would be language you would /only/ use online.

For example))))))))) (smiles)

I'm not so much trying to find the Russian equivalent of AOL speak (u want 2 chat?), but more common abbreviations. Things that would be handy to know. I'm asking because I do chat in Russian, and I just want to be aware.

Examples of internetisms I have given my Ukrainian friends: lol, brb, btw, wtf, lmao etc))) I also tell my friends that my ^_^ is :) and my ^_~ is ;).

Thanks again for your help!

[edited to add: This has become a well put together list. Yes, there is a lot of offensive language in the comments, but that's part of The Internet, and it's good to simply be aware of such things! Thanks everyone for contributing!]
