Yeah, you can resize, not just crop (thanks for that TGSC!)
The rules say 100x100, but that doesn't look too bad at 100x135 - I might up the limit to 100x150.
For now I've removed your current avatar, now that you have an alternative to host and use.
[edit] Also, I'd recommend using something better than an AOL email address if you want to actually receive any automated emails. My girlfriend runs a site that used to involve quite a bit of emailing members (a directory of beta readers for stories - effectively like editors who look over and find typos and grammar problems) and a lot of the emails became delayed or failed. More recently it has become automated, and within a few weeks our server was blocked from sending _all_ emails to AOL because someone tagged two or more emails from any site on the server as spam (that's the minimum, that's about all it takes for AOL to block an entire server!) Because of that, my girlfriends site no longer accepts AOL email addresses, because AOLs service to outsiders is so abysmal. We still accept them here, but there are so many free options out there that I'd recommend you use on of those (even a Hotmail address, and I personally don't like Hotmail!)
Rant over, normal service may resume
