Spanish Internet Text Abbreviations Slang?

when i talk to my cousins and friends who only speak spanish(and a lilttle bit of english)on facebook and texting them, they use like short text abbreviations. I'm Mexican but I don't know many of these text slang, can you guys give me a few please? I already kno "tkm" is te quiero mucho, "bn" is bien, many other little things like that and some I see that I have no clue are ee, ke, vdd, d, abbreviations like that. if you know any please let me know! Thanks(:
