If you are new to WordPress, Graphene, or to blogging or webhosting in general, there is a way to flatten out the learning curve a bit.
I know you want to set up your site and install a lot of widgets and plugins right away, but please don't. Not every widget and plugin will work with every other one, nor will they always work well with Graphene or even WordPress. Some never get updated, and others are just knock-offs of other, better, plugins.
If you have a lot of extras installed, it can be difficult to figure out what is going wrong when something does go wrong (which it will--that's the nature of the game).
So first, install WordPress, and learn what it does and doesn't do.
Second, get to know the Graphene theme, and learn what it does and doesn't do.
Then, install plugins and widgets, but install them one at a time. Play around with each one for a day or two before you add another one. Then, if something goes wrong, it probably has something to do with the last plugin or widget you installed. The same holds true of making changes to the theme (which you should do through a child theme or custom CSS).
I know you all want a fully-functioning web site right out of the box, but really, there's no such thing. It's a matter of tweaking and adjusting, and that is best done one step at a time. (And you can always make a sticky post telling your readers what features will be coming in time--it gives them a reason to keep coming back to your blog.)
This will make your life easier, and it will make it easier for others to help you in this forum.
Thanks for reading this.
