Rekha,

Yes it was Karishma.

Another one was Kajol, I forgot her sister's name. Kajol and her sister used to chat using the same computer with same nick sometimes.Very difficult to identify.

Angeleyes was also from those days. She was still around till recently.

I think Nepalikanchi was also there. Oh I remember "Kanchi" now.

I could not locate jazmin anywhere. She disappeared suddenly after few years from sajha.

Did you play trivia? Remember some names hitting the top ranks? Rascal was one of them. Never could compete with him though.
