I had created several community tags in the first paragraphs of the first lesson of the resource
LLS:CMSPRPHTSPSTLS2014-10-03T21:06:36ZCMSPRPHTSPSTLS.logos4 and have screen shots showing them. Today they have disappeared. (Yes, I checked Visual Filters and also verified via the right click menu. I even tried adding a community tag which appears to have done absolutely nothing - no thin blue line, no tooltip info)
In addition when I open the information panel, I have an error in red "Error connecting to Send to Kindle service" ... interesting since I've not tried to send it to Kindle. I don't see any indication of problems on your Status page ...
