I'm SURE I raised this topic some months ago, but after 20min searching for it here I give up - and start afresh:
Two example users -
Eagle_Kiwi and
WilliamLee
And two example formats for the link to find their Yahoo Profiles - one is the current one in use on BBB, and the other is what would be MUUUCH more sense in there (and heaps simpler/cleaner too!).
Current link format - Eagle - searches, finds one - you click it, then get Profile
Current link format - William - searches, can't find him - even keying his ID into Advanced Search STILL can't seem to find him.
Better link format - Eagle Goes STRAIGHT to his Yahoo (360) Profile.
Better link format - William Goes STRAIGHT to his Yahoo (standard) Profile.
I'm not sure why Eagle and William give different results with the Current link, but who cares, as the "Better" one gives "better" - and consistent - results.
Exception - seems new Yahoo Ids with dots confuse either system, e.g. Spike (spike.li). But, you can't win' em ALL!
