This is the wonkiest website I use. Have you ever noticed how many people will start a new post (instead of replying or editing) and start it out by saying, "sorry but it won't let me edit ... or I can't "reply"... (I can't do either just for the record.) Sometimes I can't write reviews either. Once I completely cleared my computer (not just the cookies) and I was able to review. Then the next day I couldn't again, and then despite doing nothing to my computer, I was suddenly able to review again a couple of days later.
Every time someone has a problem we're told to clear our cookies or try a different browser. It's ridiculous. We shouldn't have to do that. Temptalia launched a Swatch Gallery a few weeks back and it wasn't working for me. She messaged me asking what kind of device I was using and what browser. Within a few days the site worked for me. That's one person's (very popular) blog and her "tech guy" - not a major corporation with (I assume) multiple programmers.
Sorry for the rant. This has been bugging me for a long time.
