The mailing list archive from the users@ and devel@ lists have just been imported. You can find them under the archive subcategory below help and development categories. This makes the archives easily accessible via a web browser (with an included search function).
From here on the plan is to move posts from the archive subcategory into the most relevant category, but it will obviously take some time to go through the archive.
During the import, imported email with matching addresses is linked to existing accounts (for example here). In the case that no matching email address was found, a so-called staged account (per unique email address) was created to hold ownership of these posts. Please let us know if there are posts from you that are now owned by one of these staged users, it is possible to manually merge the staged user into your account and give you ownership over these posts.
