As I described in a previous message, UsingEnglish.com have recently been upgrading their servers. The process is now complete and seems to have gone to plan.
The physical upgrade was actually completed at the end of January but we've been testing the various parts of the site to ensure everything still works. I'm pleased to be able to say that the site is almost 100% operational.
The only known issue remaining is that of the random irregular verb tool, which I am currently working on. If you spot anything that we might have missed, please let us know about it in the forum.
