Assalaamu alaikum wa rahmatu Allahi wa barakatuh,
Barak Allahu feeki for the link ukhti.
I got on that mailing list a while ago and have gotten more than a few beneficial books mashallah. They send them to me in English and Spanish as well (and more than one copy) so I can leave them at the masjid or hand them out when people ask about Islam as well. ETA: I wanted to add that they have NEVER asked me for money or sent me any kind of spam requesting sadaqah or anything.
While I was looking at the site I noticed this link
http://www.islamic-invitation.com/images/tree_b.jpg and had to smile. My husband brought a tree similar to this one with him from Libya but it's old and has been folded and it's completely in Arabic. Even though, I still beg him every week to help me find a frame to fit it so we can hang it up. One morning, after Fajr, he came home from the masjid and said he had a surprise for me... it was this same exact poster and we found a frame that day and he hung it up for me :-D I was so happy.
