Problem: I'll be gone from here at work in about 30 minutes.
Problem: I won't be here at work tomorrow (train strike).
Problem: while I have FTP access and suchlike to the website from home (duh... all I have to do is remember a very easy to remember set of FTP server, username, and password), damned if I'll spend my free time straightening out the problems. I got caught in that particular trap yesterday ("stubborn" and "dumb" are, quite often, the same thing), I'm not going to do that again.
Problem: it still irks the hell out of me to leave everything messed up and non-solved until Monday, though.
Solution: hurry the fuck up, "tech support", and do what I told you to do. Grrr.

In the meantime, I've been looking at various other blog-management software (through OpenSourceCMS, which is very cool, and which I found - again - from scriptygoddess, which I'm starting to love more and more with each passing day). pMachine looks to be the best for what I have in mind so far, and it gives me something to fall back on should "tech support" prove to be as incompetent as they look. MT would still be the best option, though, if only because I'm actually familiar with how it works.
Of course, if MT doesn't work, and pMachine doesn't work either, I'm in deep deep shit, and my weekend will be spent tracking down something that actually works.
