So, you have your webpage made, and you're wanting to add a link, here is how you do it ;)
Either type in the word "HERE", the name of the board you're wanting to link to or if you're using a button, the same procedure described below applies...
Highlight the text or button where you're wanting your link. Once it is highlighted, click on the "Insert Link" icon:
The Insert/Edit link box will appear. If you're wanting to link to a page within your group, click where you see the GREEN arrow. A scroll box with all of your group pages will appear, choose the page, click on it and the URL will automatically show up in the URL box. Click the "INSERT" button at the bottom of the box.
Now if you're wanting to link to a page OUTSIDE of your group, you will need to copy the URL of that page and then paste it inside of the URL box (indicated by the RED arrow). You will need to use "CTRL + V" on your keyboard to paste the link....the paste (clipboard) button in your dialog box won't work. Click "Insert" and that's it!
