After looking at a bunch of options, I’ve decided to give nucleus a try as my blogger of choice on this Yahoo! Webhosting server.
The real challenge here is that PHP is limited in various ways so the only way to really know if something works is to install and test it out. Yeah, they have a list of functions that are enabled, but there are some subtle gotchas. For example, they don’t say that when using the mail functions, the from address must be from an account on your domain. Because of this I’ve had to hack my portal a bit to allow users to email articles. No big deal, but it isn’t documented anywhere that I know of.
Despite this, Yahoo! Webhosting has been a pretty good platform for me.
