It isn't an account level thing - everyone can save and use TagSets,  TagSet saving is again working, and just seconds after saving a TagSet, you'll find it in the pull-down in Composer - from extensions as well as the RiteTag site. - SauL
Please tell us which browser extension?  Chrome?  Firefox?  Safari...?  Which OS do you use, too, please. - SauL
We are working on this, Kouji.

Best regards

Thanks, Kouji, we'll look into that.  120 retweets and 120 favorites looks suspicious. - SauL
Thanks for seconding me on this one, Mike; it's in the plans, and I'm going to try to push it through in October.  (If that sounds slow - just wait until you see what's coming... hint: the browser extension is about to do much more in sites we ride in, like Buffer, Twitter, Hootsuite, etc.) - SauL
Amyn, is your browser window at 100%?  What OS/browser, please, and we'll look into it.  Just tested, working for me in WIN7/Chrome browser. - SauL
Okay, I'll ask the guys, and thanks, always. - SauL
