In reply to Ahmad Awais.

Thank you so very much for answering Ahmad.

Ok, it might be the amount of groups I'm in (I suppose more than some 50 or 60!) but I don't use it for spam.
(All these years, never had my Facebook account limited or blocked in any way)

I will log in to Facebook a bit later and will try to find you there prior to ask for joining the group so you can expect my request.

Once again, thank you.
