First of all, welcome! There are many differences on Live versus P99 that you'll enjoy. Here's a quick one... on the Live client you can check your current and needed to level experience by just typing /ex! Have fun!
I actually fell for this once upon a time. In the early days it wasn't uncommon for my connection to drop or the client to crash. Tryed the /ex and just thought it timed up poorly so got back in and did it again. Not cool as a mage who had to resummon everything each time and med up
Yeah, because people hardcore enough about an 18 year old game that they chase down a copy of titanium are never going to have heard this one before.
