Even the 30 second search wait can get frustrating (especially with the dreaded double tap on new posts).
Don't even get me started on that double tap thing. I am probably more suspectible to that than 95+% of this forum, especially given I have to use the mousepad for the press given my mouse buttons on my laptop have become worn through over-use and I prefer to not use a mouse for a laptop, given I can use my thumbs to move the mouse whilst keeping my fingers above the keyboard. For the most part, the search wait is annoying, but if every search attempted is saved then by not having it you run the risk of blowing your entire budget on it alone, so I can understand it.
Back to PMs, I honestly believe a 60 second lag would be better. I know that I am the primary "complainant" with this kind of thing, but I guess my nature has developed in such a way over the last couple of years that if something is not right I will aim to correct it. In March for instance, I made two complaints to First S&A at once!
Maybe we should consider Mojo's point? Although I would suggest that you have to provide evidence that such a tool would be necessary in order for him and the team to accept that you have a need for it, so it would have to be request/invitation only (as with the private forums).
I though this thread was about David Cameron!
Why would I be complaining about David Cameron? I am a Tory-supporter and prospective member, after all!
