Actually IMVU has not removed their line limit in the chat client, they just expanded it a great deal. T1 is actually not one of the primary combat methods for the majority of the rp scene in IMVU is using T2 and T5 based combat, while many current rp'ers on the site think that T1 is an old dinosaur that should be forgotten. There is T1 out there on the site, and I'm glad that you found it. I've been on IMVU for almost four years, and have seen much change. I wish you luck on your work.
