You just need to download a free comic reader and that'll allow you to read .cbr files (which a lot of comics are). I mostly just download whatever I find links for. but yeah, we'll definitely have to do that. I'm pretty sure we were supposed to watch Teen Titans or Jackie Chan Adventures or whatever the hell DVDs you had.
also if you can't unzip .rar files what are you doing, get winrar or something.

Yeah I'm hoping it won't be too bad. /crosses fingers
I didn't think Spiderman could be in any of the other Marvel movie properties and vice versa because of copyright issues? Something like that. Like the X-men can't meet Spiderman can't meet the Avengers because the film rights are held by separate companies.
