Rip tapes to the PC and upload is not that hard once you get your gear and programs. This is how I do it
You need to buy a

Download Audacity- this is for recording the audio to your pc
http://audacity.sourceforge.net/you'll use this to make wav files that can be burned to cd, but are too big to upload, so you also need:

If you have made one 90min file you could upload that just like that. What I often do is to cut the tape in two so each side is sepperate. I also like to make a little file with Notepad or Word where I give information about the tape. I put these in a folder and name the folder what it is- "Saxon: Brixton. 1985 (feat. Supercat)" for example. I now need to to compress or zip the folder so I can send it. To do this right click on the folder and select "send to" and then "compressed folder". If it doesnt work, download the following and then try again:

If you use sendspace or rapidshare the link will only be good for a week, so I encourage people to use megaupload ot mediafire as the links last longer- especially if you pay them for an account- which is well worth it if you're doing alot of up/downloading.
hope that's ok. any more questions do ask as I really want to see more people getting their boxes out of the loft to make this a massive archive!
