I downloaded my RootsMagice Version 6 update the day it was announced available. I've used this software since it first came out - and used its predecessor, Family Origins. I couldn't wait to try out the new publishing online feature. So while I was waiting to go to my daughter's for Thanksgiving Dinner, I decided to give it a try.
The publishing feature was quick, efficient, and produces a very nice website. Not all events publish and I noticed that sources attached to the person rather than an individual event, are not available. I particularly liked the fact that my color coding of family lines transferred to the website.
There is no way to search other sites uploaded for My RootsMagic. You can only view the sites if you have the URL. Very different from most family tree websites. Depending on your goal he uploading the website, this could be desirable, or not. That feature certainly adds a measure of privacy. I'm sure that if the URL to your site was published anywhere on the Interest, search engines could pick it up.
I'm sure I will be making changes - it's so easy to just re-upload, although you can make no changes on the actual website. There is a file size limit, but I could have added much more. I don't have many attached photos but I'm sure that would affect the file size considerably.
I suspect RootsMagic will also be making changes and adjustments over times.
I have had a web presence for over a decade, so I don't mind sharing the URL to the new site, if you'd like to take a look!
