I'd like to be able to give MC some free advertising!
I do a bit of tech support for people in my local area. I'd guess that's probably true of at least a fair number of us here (if nothing else but for our families).
I find I do a fair number of nuke-n-paves (wipe and re-start from scratch). I always like to make sure to install some of my favorite, non-evil applications for the people I'm helping out, including media players, web browsers, and whatnot.
I usually hook people up with CCCP and Media Player Classic, Firefox with Adblock Plus and Filterset.G updaters enabled, TightVNC for easy remote tech support, ZipGenius, and a few other utilities that I use regularly.
Unfortunately, as much as I'd like to, I can't pre-install MC for them (at least I don't think I can) because as soon as I install it, their 30 days would start ticking. (Am I wrong on this?) It might not be a terrible idea to have MC switch to start the counter when it is first launched! That way I (and probably others here too) could give it cred where cred is due. I honestly think some of my clients would end up hooked if they took the 30 days. It might take them a while to check it out though, and if they find they only have 3 days left it'll probably leave a bad taste.
Certainly wouldn't be a terrible idea for marketing MC as a "free trial" product anyway!
