The differences go far beyond "making a call" and "answering the phone," although that's an important difference. Rather than find your email inbox crammed with numerous messages on various subjects, when you come here everything is organized.
For a big difference, there is a Moderator here, so that inappropriate posts can be deleted. Posters can be banned. Messages with profanity, racism, general personal insults, a commercial nature or just plain spam can be deleted. I've been Moderator here for 15 years, so perhaps you can imagine that I've seen it all and dealt with it all. There is a Notify Moderator button here so that you can easily report such posts and bring them to my attention for quick action. It doesn't get used much, but when it does I take care of the issue and most of you never know there was an issue.
For another big difference, threads stay organized here, all under one link. And not only are they all together, but they're conveniently arranged in chronological order. No need to search the archives and get a mish-mash of messages from different threads that may or may not include what you were looking for.
Would you rather save dozens, scores, hundreds of emails, or have a single website where everything is always ready and organized for you?
For yet another difference, you can post images here. Messages sent to the Healeys Mail List strip away attached images, forcing you to post them online somewhere, and then link to them. And they may not be there in the future as URLs get deleted or changed.
You can have a snappy signature line here, complete with a photo if you like.
There is so much more here than just this one forum. Check out
the forum list and note that there are classified ads, activities lists, "The Pub" for general discussions, humor, motorcycles, etc.
I understand the reluctance "to change," and the Healeys Mail List appeared before the British Car Forum, so there are some who are happy in their rut no matter the comparative features. And some just relish playing the role of contrarian and insisting that their rotary-dial desk phone is just as good (or better!) than a smart phone. And there's nothing wrong with having options, but I think by any objective standard, we'd all be better off if we pooled our efforts in the superior medium. (But I also realize that given human nature, it will never happen. Now where'd I put that hand crank - must start the car for the drive to work...)
