Pembers' Ponderings

 

Made with a Mac

Dear Reader,

This web site will no longer be updated. In fact it might have already vanished next time you try to find it.

I started the site in 1997 in order to make use of the 'free' web space offered along with pay-as-you-go dial-in e-mail, Usenet and Internet accounts, firstly with Unet, and then Freeserve, Wanadoo, Orange and finally EE who have now withdrawn dial-in access as from 30 October 2014.

If you have found any of these pages useful, and think you may wish to refer to them again, please feel free to download all or any part of the site for your personal use (the total size is 15MB).

It is not clear whether EE will allow the extant websites to languish following the termination of dial-in access (at least for the six months stipulated in the original Freeserve terms and conditions), or whether they will delete them immediately. They were quick enough to switch off my T-mobile PAYG phone when they took over the contract.

Kind regards,

Alan

(and Pembers the Frog)

These days test cards are often used merely as a way of identifying a satellite link and long gone is the era when even outside programme hours television stations still had an appeal and a personality of their own.
