Hello Maltese and a very warm welcome to The Royal Forums.
I am absolutely sure that you've come to a place where you'll find the people warm and friendly and always willing to discuss just about everything under the sun as it relates to royalty as well to everyday life. I've made some wonderful friends here and I'm hoping that you will do the same.
The Royal Forums have their own thing where you can send and receive PMs (Private Messages) between members here. It has definitely become the springboard to exchanging emails between some of the people I have become friends with here.
There most definitely is an area that is dedicated to signatures of royals and it can be found here and I imagine autographs are discussed there also.
Sit back, relax and be prepared to spend many, many happy hours here with this wonderful global community as I have. Its just about the first place I come to when I wake up and the last place I go to before sleep. Like you, I'm pretty much homebound due to being retired on a fixed income and have ears that don't work too well and legs that most times act if they're made out of jello so finding TRF has been a blessing for me and I hope it will be for you too!
