I've been transcribing for FreeCEN for a while. I used to have copies of the census sent by post, but the last batch was scanned, the images put onto CD and I got the CD by post.
It really is easy. Depending on work I can usually get about 10-20 pages done in a week, so it takes a few weeks to complete a district. As far as I'm concerned, the advantages are that not only can I see the original images for my family, but I can also do lookups for others, and I get a better "feel" for the place.
91 is now complete for my main area, so I'm now doing 71. 61 will be next apparently.
Once I've finished these, I'll move onto another parish of interest which hasn't been done yet.
At the end of the day, it does benefit everyone.
