i heard that you can not re add a contact once you have deleted and blocked that contact well i would like to but seem not to be able to i have re added them but they stay offline and i am unable to email them also if any one knows how to sort this id be very gratefull
You should be able to see them online again when they're, unless they have blocked you.
If they are sure they haven't blocked you, then there must be a problem with servers.
Also you should be able to send e-mails to them, nothing can ruin this action imho. In contact list right click on one of those contacts and select Send another>Email (email@com) [Menu items may not reflect the original English version]
