I realise that this is an old thread but I'm in the same situation and would love some advice. I've been blogging with pMachine for about 4 years now and find it very easy to use. Unfortunately, some spammer decided to use my site to relay their messages and the account was suspended. Given that I will have to hack around in a bunch of unsupported PHP to try to close whichever holes they exploited (as yet, I have no idea), I'm considering using this as an opportunity to transition to WordPress 2.7. The question I have, though, is whether or not this will be worth the effort? Is WP inherently less likely to be a target of spammers and, hence, less likely to cause me to have to wade through lots of someone elses PHP? Given that it is a platform with ongoing support, I assume it is less likely to be attacked successfully but this is merely a guess.
Another question I have relates to migrating my pMachine content into WordPress. I've found some scripts that allegedly do this and some other advice on the web but would love to hear first hand from anyone who has done this. How straightforward was the migration and are there any TCH-specific gotchas I should be aware of?
Thanks in advance for any advice.
