firstly, thanks dezina for your message and recommendation.

secondly, you mentioned "good and recommended brand". but i am confused. are SSL certificates like washing machines, some allow you to quick wash, some have delay timer, etc.?

or, put it another way, what does a good SSL certificate consist of?

you might have realised i am repeating the same question asked in my previous message. the reason is, i would like to learn more about good elements of good SSL certificates and compare different brands, though i may end up getting the one you've just recommended

thanks again.
