Same problem happened to me - Must be a bug, a cache problem. I finally managed by taking my time: I 1st deleted it - waited until the old avatar disappeared - waited some more or else the old one came back... to be sure I let a day pass, only then did I manage to change it!
I just tried - also using Chrome, the latest dev version with the Diigolet. I had no problem - see here
??? maybe it was a temporary glitch? Have you re-tried after relaunching the browser?
PS: when I can't bookmark a page, like flash (swf) pages, I use the Add New Bookmark page. To make things easier, I use queri.ac, yubnub (eg.: with yubnub I just add "diiadd" in front of the URL) or the alternative bookmarklets
Capture a screenshot, annotate it with rectangles, circles, arrows, lines and text, crop any part of the screen shot and save it as a file.\nInstall
diigo Integration to come!
I went though a period like that, and one day I noticed that I could. (But now that I can, I realise it's very rare - I try to only use it for warnings)
True, you've been here for a while now... (It just might be possible that now that you mentioned this, you will be able to soon ???)
Meanwhile, why don't you try posting to groups?
Maybe they could(should?) create a request form with guidelines to agree to ?
PS: There were some pages that got so many it became a real issue.
There's a big misunderstanding about SOCIAL software - definition of 'social':
- characterised by friendly companionship or relations. (spamming is NOT friendly, it's rude and selfish)
What's up?
PS: You can still search them from this page: https://groups.diigo.com/index
