Obviously this would not be a topic if the PHP fixes had been released as we and many other board hosts wished. We all have our own opinions and decisions on things like this, go left or go right. Bunt or swing for the fences. Go for the win or go for the tie. I would only hope that anyone with an opinion on this has read enough to know that there is clearly no vast majority of opinion.
In reality, we have decided a path that serves both - leaving the board fast(er) and still making search available to members, via our moderator staff. Should you have a specific topic in mind during this period, let me or another moderator know what you are looking for and we'll do our best to find it and provide you with the results.
You can be assured that once PHP gets a speed/security fix available we'll have it installed and once again open up search.
