SMF 2.1 Support: This is built into SMF 2.1 as ACP > Maintenance > Ban Log
On heavily customized sites, we would expect most forum admins to check the error log on a regular basis, particularly in concert with our Error Log Counter (http://custom.simplemachines.org/mods/index.php?mod=2441), being 'on top' of errors as they occur.
One thing to note about the error log is that it groups different kinds of errors together, enabling admins to look at errors on different severity, and one oversight seems to be that errors from banned users are lumped into the 'user errors' group, rather than having their own category. On a site with multiple troublemakers, it will be easier to have these all in one place within the error log, if you're already checking it regularly, without you having to also check the ban log.
Enter 'Ban Filter'. This provides a filter in the error log area for bans, separately to user errors and so on, as illustrated.
Includes the following languages: English & Turkish.
Now this should be a standard feature. Thanks SD team.
