I don't write many posts, but I have noticed that some people are so impatient on "why this" and "why that". The Mods are doing a great job for a FREE, YES FREE, hosting site. Instead of just posting YOUR problem, browse through other posts, you may get some insight in what is happening.
I host 2 free sites and If I wanted 100% uptime, I would have to pay for it, but I, and my sites can cope with downtime. So instead of just wingeing, give the lads a chance to sort things out, or PAY!!
