I'd recommend buying Trillian Pro. I donated $5 long before Pro. was even announced, so I was given a complimentary 1 year membership.

However, if you're considering this you might want to wait ~3 months for a new version. Also make sure you are buying it for the program and not the "membership" (constant news updates, fixes, new releases, etc.) because as it stands now those were empty promises and the Trillian "members community" is up in arms about it.

Also, when you buy it you get access to the members forums which include a plugin development forum where you can grab plugin betas, alphas, etc. and also give ideas to 3rd party plugin devs. You also get access to the members section of the website which has announcements from the company and official plugins.

So while yes, it's probably possible to get a warez copy... IMO you should go for a membership so you get what's mentioned above... maybe it's just my thing by to me "plugins are everything" ( Well... 90% )
