The old forum will stay as an archive. In a few month it will be read-only. All threads still needed should be moved here. If you have a topic on the old forum you want to continue here, there are two options:
- Copy everything over here, but it would be a lot of work and not especially nice to read.
- Copy only the most important part, so that the discussion may continue over here. Add a link to the old forum on the first post, so that interested people may read everything over there.
If only you want to save it, just copy it to your hard disk.
