I have 100MB at telus

but for every entry i guess i would have to edit html

I could put up a "Blog page"
and update it every so often but how might i automate that kind of thing?
and what should it look like??

well that becomes more and more just a website. If you would like to setup an actual blog look into what your telus hosting has to offer. for something like Wordpress which is one of the most popular blogging setups you will need a MySQL and PHP server. MySQL is a a database and PHP is a server side language allowing you to have a fully functional blog that allows posting without updating each page.

If your telus doesn't have a MySQL server which for this I'm assuming it doesn't, then you can go to www.000webhost.com and connect your telus blog to the MySQL database that they can offer you for free.
If your serious about setting up a blog the $50-$70 a year by using dreamhost or godaddy would be worth it. 100mb isn't very much room to play with.

If you would like some examples of what other peoples blogs look like then look around dreamincode.net a lot of people will have links to their blogs in their signatures.
