Well, I'll tell you what I've been thinking about..
All my conversions for Mackie I'm going to leave where they are.. they're Mackie's of course.
The main webpages I was thinking of leaving where they are with non-TCS links being linked to from the main site.
Any of my other Trek conversions that were non-Mackie, I was thinking of moving somewhere to free up space.
Any modelling programs and similar files I was thinking of moving somewhere to free up space.
The main site I'm thinking of spliiting into three parts.. a Trek part, a programs/stuff part, and a Babylon 5 part. The Trek part I'm thinking will be my current lineup of Trek stuff, the SFC 2/SFC 1 converted G@W ships+the Trek lines from "The Station". This part will need a lot of storage space.
The other part will be a tute/programs/stuff/other meshes site.. some educational stuff up there. This'll need some room.. not too much. This'll be the main part of "Mare Imbrium".
The last part will be all the ships from the B5FC project, any new ones I get together, the B5FC forums (once converted), any new B5 ships/stuff that comes out I can gather, etc. This'll be the resurrected "The Station". Will need some space, but not nearly as much probably as the Trek section.
The site on Mackie's will become more of a three-edged portal, with the classic site still being there, but any existing links pointing to the new locations for the old files... and all this'll be behind a new entrance designed to point people where they wish to go. This way, any page links will still work, but some individual file download links in the forums may change.
Think it'll be awesome once it's all done.. but it's more going to need gobs of space and gobs of time. :p
