Many of the abbreviations used in chats have pretty much become universal and a lot have become creatively humorous thanks to many regulars in those chat rooms.
Usually people will keep in contact through e-mail, regular mail, and sometimes phone calls.
And if you do somehow find a way to meet, hey more power to you!
Considering that this relationship maybe over a long distance the chances of you meeting the other person are almost next to none.
But don't let this stop you from keeping in contact of each other.
Just be careful when getting into a long distance relationship with someone, it may seem great and everything, but something just might be lurking under the surface.
