I have lost many, many, first class domains.
Lesson 1:
Listen to Supercod - it is your responsibility and noone elses and renew now.
Lesson 2:
use a good isp - for the record I have lost most domains through vi.net now active isp - complete cr*p
They sometimes choose to remind you by mail and that is it - no emails - nothing and they once resold a valid domain of mine to someone else even though I still owned it - they even redirected the nameservers to the other site. (I got it back)
Lesson 3:
Many isps still have control after it has officially expired - during the various stages of deletion - so call your isp at once and if its .uk then call nominet - they are usually very helpful.
Lesson 4:
You can register with all the dropcatchers e.g. pool.com, snapnames, enom, many others, if you want a chance of getting it back. You will certainly not be able to 'hope' noone reregisters it and you will try later - dropcatching is very competitive industry.
Registering with just one dropcatcher is not enough as they all have only a percentage chance of getting it.
If your name is very good and short or if it has high traffic then chances are you have lost it for ever as many of the catchers filter these into their collections before even offering them to the public.
I
am sure I
am still losing them . . .
Do it now!
