Thanks again for the replies, there is certainly a lot to think about. Roger, thanks for replying again even though I've already tried to pick your brains in person!
This is what I would like to do:
1. Keep and update old pages on constellation starlore
2. Present some pages on astro activities I do eg ATM stuff, maybe a little astrophotography
3. highlight things/places/events in Western Australia
4. Start a blog
5. Maybe start a new project idea presenting themed info, if I get through the above!
The more I think about it the better the idea of a blog becomes, because it could encompass 2. and 3. nicely but the starlore pages really need their own domain space. So would the project in 5. I was hoping to keep most of it together but if two new domains and a blog are the way to go I'll try that. I'm not that interested in having comments enabled on the blog (I'm happy just to be talking to myself
) The blog would be a once a week thing, definitely not every day. I am amazed at those people who do blog every day, and how much they have to say!
Blog stuff: I've already had a look at free CMS's on the go from here
http://www.opensourcecms.com/ and I saw Joomla! on there but I was shown Silverstripe as a demo from the person who put me on to the site and I thought I'd give it a go as it looked pretty simple but ran into a coding problem trying to get it to run that I couldn't understand how to get around even though I looked at the FAQs and help forums. Anyway, the long shot from this is that while my current ISP provided php it doesn't provide a MySQL database unless I'm paying big bucks for a business site, so I can't run other easier CMS's like Wordpress.
So from what the rest of you have said I really need to look elsewhere for a domain host, one that will also offer MySQL as well as php.
Any further comments following on from this from you helpful folk?
