When employers are funny about people using their Internet services for personal things, they may have a teeny, tiny leg to stand on.
Case in point: those of you who noticed parts of this website being kind of broken early this week? That would be because last weekend I uploaded some personal stuff in a subdirectory of this site on the server. All worked swimmingly too! The problem was that apparently along the way, I introduced some code that wreaked quiet havoc on the rest of this site, and after a six-hour increasingly frustrated session of searching through pages and pages of php to find the culprit, I eventually decided that my life was going to be just so much easier if I deleted that personal stuff from here (thus solving the brokenness indirectly) and moved it to its own hosting account.
