xThreads: Plugin name = (1) ?

It's probably a language issue - that is, I only have English names for everything.
You can copy the 2 xthreads.lang.php files in inc/languages/english into the folder with the language you're using.

I unzipped ~10 plugins at once and might have made an error while getting all the files into a single upload folder. Either way, the new release looks good; Thanks for the XtraHuge plugin Zinga.
