As some forums have merged, titles changed, descriptions still to do..
Would it be worth reviewing stickied threads? Some are very old and could do with a revamp. Not to mention some information could now be out-of-date.
For example 'Education and work' has 4 stickied threads for beginners French, German, Spanish and Japanese. Why not have one thread - 'Languages for beginners', improve the content, add fancy banners, have votes/ideas on what stikied threads there should be/forum comp to create new and improved threads.. I can go on
This looks like a quick-win for our community.
