I'm using Firefox.
I can't see to find any options that will let me attach images/pictures/etc or quote someone else's posts. Can someone help?
To quote another post, you can click on the "Quote" button at the upper right of the text editor.
For uploading images, click on the "tree" icon next to the chain in the text editor toolbar above and navigate to the image you want to upload.
If you want to add an attachment, that is available at the bottom of the text editor under the subscriptions header. If you need any further help, feel free to send me a PM or reply here.
What I am looking for is an option to add an attachment from my computer, not from a link. Is that possible?
Unfortunately, that feature is not one that the community members can utilize at this time.
However, there are several free image hosting sites where you can upload an image and then link to it to as described earlier include it in your post.
