since you asked i just tried it...its pretty slow with the huge tables used by the boards. i can login ok. hard to look at, very broken up on the screen with the way blazer shows it. did i mention slow? its just a lot of data to push thru the connection, granted mines not a great one from my house right now. i think posting will work but its taking a long time to come up. yea it works...see my reply in this
thread.
so yes you can but its not too user friendly to do so. however don't let this decide whether you should get one or not. you'd have to pry mine from my cold dead fingers. i love the ability to grab maps off yahoo right after someone calls and gives me the address of some place i'm about to meet them. verichat is like trillian for the treo. plus all the other great pda features, i cant live without the datebook. check
treocentral.com and their discussion boards for more info. i love the treo 300
