Installing and upgrading help

Here's the response from my webhost: Hello Guido, Thanks for the update. This issue has been fixed. I have increased the memory limit to 64M in custom php.ini and for whole public_html folder using following line in '.htaccess' under public_html directory. ----- SetEnv PHPRC /home/domainname/public_html/moodle -----! Please note that we can not increase it more than 64M as your account is hosted on shared environment. Now can proceed further to install Moodle as our server environment meets all minimum requirements. Please feel free to contact us if you require any further assistance. Yay! That's all it took Is 64MB enough though? It'll be a small site, but if 70MB is recommended as a minimum, I might run into trouble.
