XFMG imports everything from Photopost Pro and vbulletin profile albums. But there is no redirection script yet. Which means that links to your vbulletin albums or your photopost pro install will break after migration, which is bad for your SEO and usability. @Chris D has recently mentioned this about it: So its time to have this developed. Who is with me on this? Multiple people will need this, so we might as well share development costs.
