Writing User Articles in dpReview

I Plan to write a series of Articles on dpreview. This Article serves the purpose of:

• developing my skill of writing Articles in this tool
• document my experiences and learning for my later reference and hopefully help of others
• explore which features are available
• what is the behavior of Articles. E.g. Can I edit an Article after publishing it ?

This Article will now be published. Next I want to try to create two other Articles and then go back to this one and create a simple Table of Content with links to those Articles.

If anyone reads this in this infant stage, pleas post comment to the following subjects:

• links to documentation on capabilities and behaviors of Articles on dPreview
• If you consider writing Articles on dpReview and have a question, please post it and I will try to find the answer and include this in this Article Series.

Questions I have so far:

Q1) How to add tags ?
I found  the "Tags" Button. But no list of used Tags. This is of limited use, if everybody defines his own tags.

Q2) How to solve the performance issue "waiting platform.twitter.com"?
Whatever I want to do, after pressing a button I need to wait about a minute until I can do something due to "waiting platform.twitter". This was annoying when reading dpreview. But now when writing on multiple Articles it seriously slows me down.

Q3) List of all formatting options

Q4) How to add pictures via a link ( image resides on another server ) ?

Q5) How to add an image of say 200 x 300 px which links to a bigger one, preferably in dpReview User Catalog?

Q6) After an Article has been approved for publishing. Then I edit it. Does it have to be approved again ?
A6) The edited version was instantly published. Great :-) 

Learning so far:

L1) When pressing publish it seems the Article is not published instantly, but only after dpReview staff reviews it. It took 15 hours to be published. Not bad! Thanks for the great work!
