Hey there
This is very easy.
1. Under the
Administration menu on the right, about halfway down you'll find the
Languages link.
2. Click on this and when the Language page loads, from the top drop-down "select language" choose
English and wait for the page to load (you don't need to press anything..)
3. When that page loads, find
Select Topic and choose
Text. Again, no need to click anything else, just wait for the next page to load.
4. When the Text page loads, you can search for the text you want to replace by pasting a few words of it into the
Apply Filter text area and clicking
Apply.
5. In this case, you are looking for the
Welcome text. When that comes up, put in what you'd like to appear on the page into the
Value text field and click
Apply Changes.
That's it! If you find sentences or verbiage that you're not thrilled with, you can change them here in the Languages area. Just search using the method I've given and you can find anything.
Edited to add: you can change email verbiage, error verbiage and labels here. It's all located in the
Select Topics drop down. If you can't find something in one topic, choose another. Pretty simple!
HTH!
