Several tutorials were pointed out to me:

The following can be accessed from the Homescreen:
1. Getting started with Wolfram Programming Cloud: http://www.wolfram.com/broadcast/video.php?c=362&v=1051
2. A Fast Introduction for Programmers: http://www.wolfram.com/language/fast-introduction-for-programmers/interactive-usage/
3. "Thing to try" notebook: https://programming.wolframcloud.com/objects/7ea9a27a-1ea8-4df6-9f99-8995ef312428
4. Click orange "View all>>" next to "Introduction and How Tos". It will open the following page in the Documentation Center: http://reference.wolfram.com/language/howto/WorkWithWolframProgrammingCloud.html

The How To pages in the Related Links are very helpful.

Is there something more you were looking for? (Try to be specific.)

Ampo and Pete,

Thank you for taking the time to post these. I sent your reports to developers.

I point out again that this thread is for problems accessing Wolfram Programming Cloud, not problems using it.

1-st bug disappeared, thanx, Next:

after sometime in the WCloud i see the note "Page crushed", and work is finished without mercy.

I use Opera 20.0.1387.91, Windows XP 32-bit

When i try to authorize in the cloud (my usial Wolfram ID & password), i receive an answer:

Unknown request token "f98ddf2e3561c719f5093651ca090791053ae8bd0"

2-nd attempt:

Unknown request token "ba0c47f2ec89d9faa2885e1070039448053aeac38"

and that's all.

When you take away this problem - please inform me by e-mail - i'll try again and write here the new result.
